PHiLARC - The No. 1 Choice of Welders

PA-7011-A1

AWS Specification: AWS A5.5 E7011-A1

JIS Specification: NONE

Other Specification: NONE

 

I. APPLICATIONS:

Welding of 0.5% Mo heat resistant steel, pipes and pipelines such as API 5LX-x52~x6

II. DESCRIPTIONS:

PA-7011-A1 is a high tensile strength steel cellulose coated electrode for all-position welding.

Heat resistance of the weld metal is excellent.

Slag removal and bead appearance are good.

III. NOTES ON USAGE:

  • Pay attention not to use the currents exceeding the recommended currents, because the proper currents for cellulose type electrodes are lower in comparison with those for ordinary type electrodes.

  • As this electrode is prone to absorb moisture, store it with care.

  • Dry the electrodes at 70-100ºC for 30-60 minutes before use.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
